Using It on the Job

1. Isolate Power: Always shut off the main power and gas supply to the ducted heater at the breaker and gas meter before beginning work. Apply lockout/tagout procedures.
2. Locate Switch: Find the existing pressure switch, typically near the combustion fan or flue pipe on the Brivis unit.
3. Disconnect: Carefully disconnect the electrical wiring and any sensing tubes from the old switch. Note their original positions.
4. Install New Switch: Mount the new Brivis pressure switch, reconnect the sensing tubes, and reattach the electrical wiring in the correct orientation.
5. Test Operation: Restore power and gas. Initiate a heating cycle, carefully observing the sequence to ensure the combustion fan starts, the pressure switch closes, and the main burner ignites safely.

Limitations & Safety Notes

• Only for use with compatible Brivis gas ducted heating systems as specified.
• Gas appliance servicing should only be performed by a licensed gasfitter or qualified HVAC technician.
• Always follow manufacturer's installation instructions and local Australian standards.
• Ensure power and gas are fully isolated and tagged out before any maintenance.

When troubleshooting a pressure switch fault, always check the integrity of the sensing tubes for cracks or blockages first. A minor air leak in the tube can mimic a faulty switch, costing you a call-back if not properly diagnosed.
